LATCH-HANDLE.

SPECIFICATION forming part of Letters Patent No. 476,636, dated June 7,1892.

Application filed March 22, 1892. Serial No. 426,032. (No model.)

To (ZZZ whom it may concern:

Be it known that I, CHARLES E. HART, of New Britain, in the county ofHartford and State of Connecticut, have invented certain new and usefulImprovements in Latch-Handles, of which the following is a full, clear,and exact description,wherebyany one skilled in the art can make and usethe same.

The object of my improvement is to pro duce a strong, simple, andcomparatively inexpensive latch-handle of thin metal; and to this end myinvention consists in the details of the several parts making up thehandle as a whole, as more particularly hereinafter described, andpointed out in the claim.

Referring to the drawings, Figure 1 is a front view of a latclrhandleembodying my invention. Fig. 2 is an edge view of the handle and latch.Fig. 3 is a detail view in central section of these parts. Fig. 4 is adetail view in cross-section. Fig. 5 is a detail view, in cross-section,of a modified form of the handle. Fig. 6 is a detail View incross-section of another modified form of the handle.

In the accompanying drawings the letter a denotes the body of thehandle; Z), the latch that is supported in the latch-socket a in thehandle. This body part of the handle is made from a piece of thin metal,preferably lowgrade steel, that is bent to curved shape lengthwisenecessary to give room for grasping the handle when it is attached to adoor or like part by means of screws or like fastening means that passthrough the openings in the feet Z) b The body portion of the handle isnot only curved lengthwise, but is curved crosswise, the side portions abeing turned outward to present a properly-shaped grasping-surface, andthere is also a lengthwise corrugation 0 formed integral with the bodypart of the handle and extending from end to end of the central partfrom foot portion to foot portion. By this construction of the handlegreat strength and rigidity is given to the comparatively thin metal, sothat amuch less weight of metal may be used in its construction thanwould be required for any other form of latch-handle that has heretoforebeen made of cast metal. The form of this latch is one that isparticularly adapted to the present methods and processes of workingplate metal, and as a result an extremely cheap and durable handle maybe produced by the practice of my improvement.

A latch-socket a is formed through the foot Z), and the shank ofalateh-lever 6 extends therethrough, this lever having a fulcrumnotch eon the underside, which rides on the edge d of the socket, thethumb-piece being located upon one side and the curved tail 6 of thelatch extending on the other side and projecting underneath the latch inconnection with which the latch lever and handle are commonly used.

My invention comprises the production of a handle from thin metal whensuch handle has a strengthening-rib formed lengthwise thereof andfoot-pieces at the ends, whether such rib exists in the form of acentralcorrugation, as shown in the sectional view in Fig. 5 of the drawings,or the curved edges, as shown in Fig. 6, and such forms of handles comewithin the scope of my invention.

It is obvious that the handle may be modified in general shape andoutline in cross-section and in location of the strengthening devicewithout departing from my invention.

I claim as my invention As an improved article of manufacture, alatch-handle made of a single piece of sheet metal curved lengthwise toshape and terminating in flattened footportions and having an integralrib or corrugation extending lengthwise of the curved body portion ofthe handle, all substantially as described.
